You can do this with a regular expression, actually:
testText = '/abcaaab/abca/eeabcac/'
import re
m =
re.search(r'/(?P<x>.+)(?P<y>.+)(?P<z>.+)/(?P=x)(?P=y)/(?P<v>.+)(?P=x)(?P<w>.+)/',
testText)
print m.group('v', 'w', 'x', 'y', 'z')
Output is:
('ee', 'ac', 'abc', 'a', 'aab')
For variety, change the matches to non-greedy (.+?) and get this result:
('ee', 'bcac', 'a', 'bca', 'aab')
